Aplicação da metodologia A3 em problemas de vazamento de reatores e tanques industriais

Abstract

In the current corporate environment, companies have been trying to solve their problems by focusing on achieving improvements in performance and results, seeking to reduce operating costs without compromising the quality of the products or services developed. An industrial model focused on continuous improvement requires demanding results. In the 1980s, the Toyota Production System, or Lean Manufacturing, was pioneered, proving that Japanese vehicles lasted longer than American ones, becoming synonymous with quality and efficiency in order to stimulate simplicity, synthesis power, and focus of the improvement agents, Toyota developed the A3 Methodology, enabling process improvement by setting and following up on goals, as well as target performance conditions. The improvement objectives and requirements are defined, what the root cause of the problem is, what changes can be made, and what control measures must be checked to analyze the results. This methodology follows the same logic of PDCA (Plan - Do - Check - Act). In this context, the present work consists of the application of A3 Methodology in an industrial unit producing agrochemical products, in order to solve problems related to the leakage of chemicals from reactors and tanks. The paper presents, describes and analyzes the steps of the A3 Methodology, oriented towards the application of the problem at hand, presents, evaluates and discusses the results obtained from this implementation.
